APPARATUS FOR DYEING YA Application filed June 3, 1924, Serial No.

The present invention relates to a new and improved process for dyeing of yarns in the forms of hanks, fabricsand the like in which the goods to be dyed are introduced into chambers in which the liquid is kept agitated. According to the present invention the liquid is forced in a periodically changing direction through said chambers by means of a pump large enough to draw the whole liquid at a time from one chamber or chambers and to press it into the other chamber or chambers in such a manner that the whole mass of liquid flows with uniform speed through the chambers.

Experience has shown that an uniform dyeing for instance of artificial silk and the like can only be expected with certainty, if a relatively very large amount of liquid passes over all the parts of the goods and if the liquid is very frequently regenerated and cleaned from impurities taken offthe goods.

The invention relates moreover to a machine having a pump by means of which all the dyeing liquid in the apparatus is positively directed and in periodically changing opposite directions. The liquid is positively forced into the chamber containing the goods and is drawn off again the liquid pass ing with equal speed and in equal quantity over all and any part of the yarn,'etc. All the liquid is circulating in a given direction at a comparatively high speed and the direction of flow is reversed frequently the pump being sufficiently large to keep the whole of the liquid in motion. After. the liquid has passed over the goods it is treated by the addition of dye-stuff, by re-heating it, etc. be-

fore it passes again to the goods.

To keep the whole amount of liquid in motion comparatively large pumps are necessary and to simplify the apparatus a rotary pump is used. The rotor of the pump is placed in a chamber forming part of the apparatus, the chamber Wall forming part of the pump casing and the rotor is arranged in a ring or casing furnished with a guide blade or liquid deflector.

In the accompanying drawings a part of the apparatusis illustrated as the preferred construction of the invention.

Fig. a shows a section on line CD of Fig. l.

The apparatus shown comprises a casing of wood in whichtwo vertical members 5, 7* a e provided into which the goods to are introduced. The chambers 55, 7 are separated from a third vertical chamber 20 by partition walls 8. The upper ends of the chambers 5, 7 are in coninnniication with each other by a horizontal channel In the walls 8 of the chambers 5, 7 arotary diversion or change-over valve 9 which valve can be rotated by-means of a shaft 10.

By the rotation of the valve 9the one or the other chamber or 7 can be connected with the suction space 12 01 21 centrifugal pump 13. In Fig. 2 thechamber 7 is shown in connection with the space 12. The pump has a rotor 14, which is mounted on a shaft 15 and is driven by a motor 28. The rotor runs inside a ring 16, which is let into the wooden sides 17 of the apparatus and is furnished with a guide blade or deflector 18. The ring 16 leads the fluid arriving axially to the pump 13 into a passage 19, which carries the fluid upwards into the uptake 4 whence the fluid flows intothe regenerating chamber 20. By rotation of valve 9 the chamber 20 may be connected with either chamber 5 or 7 and the liquid may be directed first to chamber 5 or chamber 7. The guide-blade ring 16 has a flange 21, on which the rotor slides with a packing effect, so that the suction side of the pump is shut off from the pressure side. The direction in which the pump runs, and the direction of movement of the liquid through chamber 20, is always the same, the direction of movement of the liquid through the chambers 5, 7 and the goods to be dyed is, however, altered periodically as the valve 9 is reversed. The latter is mounted in metal rings, which serve for guiding the metal valve 9. For the reversing of the valve 9 an automatic reversing device driven by a motor 23 may be provided, which, by means of a chain 24 and chain wheels 25, 26 periodically rotates the shaft 10 to the extent of 180 degrees.

The pump and all the parts thereof are sufliciently large and speed of its rotor is such that the whole column of liquid within the chambers 5, 7 is continuously and uniformly moved and the 7 liquid .is forced through the goods at each spot of the crossis inserted section of the chambers With equal force, Whether the liquid flows upwards or downwards. The pump exerts a sucking action at the end of one or the other chamber 5, 7 according to the position of the valve 9 Whilst the liquid is pressed into the other end of the respective chamber. At any position of valve 9 the liquid flows in the same direction through chamber 20, in Which chamber steam pipes or filters or both (not shown in the drawing) may be arranged to reheat the liquid to the most effective temperature or to clean the liquid from the impurities which the liquid takes of the goods by flowing therethrough. By means of a suitable conduit 2U" additional dye stuff may be added to the liquid in the chamber 20. Each time the liquid has passed the chambers 5, 7 it is again regenerated and attains its full active power and is kept in its most perfect condition throughout the operation Any number of chambers 5, 7 may be used and the Walls may be provided with suitable openings to introduce the goods.

The uniform dyeing of the yarn is effected by simple and cheap means, the pipes, valves and the like outside the fluidcontainer are dispensed with and pen stuffing boxes or joints, Which Would leak after a short period of use under the prevailing pressure and temperature, are necessary.

What I Wish to secure by U. S. Letters Patent is:

Apparatus for the dyeing of textile fibres, yarn, fabric and so on comprising a casing, chambers to receive the goods to be dyed communicating With each other, a regenerating chamber arranged between the first-named chambers, a pump to suck the liquid from the lower end 01": one of the chambers and to force it into the lower end of the other chamber, a reversing valve interconnecting each of said chambers With the pump and With the regenerating chamber substantially as described, the rotor of the pump being set in a ring furnished with a deflector for the liquid, said ring being provided With a flange adapted to prevent leakage from the suction side to the pressure side.

In Witness whereof I affix my signature.
